Patent EP-0440303-A1 (EP)
Inventor: BOSMAN BOUKJE WENDELINA
IPC: A23L13/00
Filed: 1991-01-30
Abstract: The present invention relates to a tripeptidase of lactic acid bacteria in isolated form as well as to uses thereof, e.g., in the preparation of foods such as cheese, whippable products and meat products, or for preparing antibodies against the tripeptidase. The invention also relates to recombinant genetic information coding for the tripeptidase and transformed organisms expressing the tripeptidase. The tripeptidase can be isolated from  Lactococcus lactis  subsp. cremoris Wg2 and specifically separates the N-terminal amino acid from tripeptides. The hydrolysis activity has a temperature optimum at about 55°C and a pH optimum at about 7.5. The molecular weight is about 105 kD and the isoelectric point about 3.7. The tripeptidase is sensitive to EDTA, dithiothreitol and β-mercaptoethanol.

Abstract: A semiconductor device is formed by a semiconductor body (1) having a substrate (2) on which is provided a channel-defining region (10) extending between input and output regions (20) and (21). The channel-defining region (10) has a channel layer (11) forming a heterojunction (12) with at least one barrier layer (13) to form within the channel layer (11) (e.g. by modulation doping) a two-dimensional free charge carrier gas (14) of one conductivity type for providing a conduction channel (14) controllable by a gate electrode (25). A potential well region (30) is provided between the substrate (2) and the channel-defining region (10). The potential well region (30) has at least one potential well-defining layer (31) forming heterojunctions (32) with adjacent barrier layers (33) to define a potential well which is empty of free charge carriers of the one conductivity type when no voltage is applied between the input and output regions (20 and 21) and which is sufficiently deep and wide to trap hot charge carriers of the one conductivity type which are emitted from the channel-defining region (10) towards the substrate (1) when a high lateral electrical field exists in the channel-defining region (10), thereby constraining the hot charge carriers near to the gate electrode and enabling an improved output impedance where the device is an FET. 
     Where there are a number of channel layers (11 a) placed one on top of another then generally this will mean that modulation doping occurs via both heterojunctions (12a) bounding a channel layer (11 a). In order to suppress additional scattering caused by the rough inverted interface (12'a) the barrier layers (13'a) between adjacent channel layers (11'a) each have a first subsidiary layer (130a) doped with impurities of the one conductivity type for modulation doping the underlying channel layer (11'a) via the normal or second interface (12"a) and a second subsidiary layer (131 a) doped with impurities characteristic of the opposite conductivity type and sufficiently thin and lowly doped as to be fully depleted of free charge carriers at zero bias adjacent the inverted or first interface (12'a) for inhibiting the provision of free charge carriers of the one conductivity type in a channel layer (11'a) at the inverted interface (12'a).

Abstract: A communications cable (20) indudes water blocking provisions which are microbial resistant The water blocking provisions include a microbial resistant water blocking member (35) comprising a laminate which includes two tapes (37-37) with a superabsorbent powder (40) therebetween. Advantageously, the superabsorbent powder on contact with moisture swells to block further intrusion of moisture and to prevent its movement longitudinally within the cable. The tapes of the laminate may be non-cellulosic such as for example a spunbonded polyester material which has suitable tensile strength and which has a relatively high porosity and further which prevents the growth of fungus. An adhesive system (42) included in the laminate is sufficient to hold together the tapes and and the powder without inhibiting swelling of the powder on contact with water.

Abstract: In a portable circular saw, depth of cut adjustment is effected by pivoting movement between a shoe (24) (which supports the saw on a workpiece) and a motor and gear case housing (26) (carrying the saw blade (12)) about a pivot connection (28) rearward of the housing (26). Forward of the housing (26) an upwardly extending arcuate depth slide (38), fixed to the shoe (24), slidably engages an arcuate depth guide (40) carried by the housing (26) Towards the upper end of the depth slide (38), and in generally fixed relation to it, a clamping assembly (42) selectively clamps the depth slide (38) and depth guide (40) together to establish a depth of cut adjustment setting. The essentially fixed relationship of a locking knob (100) of the clamping assembly (42) to the shoe (24) mean that the operations of changing depth adjustment setting may be made without changing operator's hand positions on the saw. In addition, the fixed position of the knob (100) in sawing operations mean that by design, suitably shaped, sized and positioned, it may be used as an auxiliary handle in guiding the saw in sawing operations.

Abstract: A production method for an endless track bushing (7) wherein high-carbon low-alloy steel is selected as a bushing material, the bushing material is quench-hardened without pre-carburizing the bushing material, and then tempered. In the quenching-hardening, the bushing material (7) is induction-heated from an outside surface of the bushing material only so that an inside surface of the bushing material is heated to a temperature above and close to a transformation temperature of the high-carbon steel, and then the heated bushing material is cooled from the outside surface of the bushing material only. In the induction-heating, the bushing material (7) is not heated from the inside surface of the bushing material. The bushing (7) produced according to the method has a substantially constant and high hardness throughout the entire thickness of a wall of the bushing material.

Abstract: A laser is used to generate a laser pulse (24) for removing hard dental material, the laser pulse having two consecutive pulse ranges (23, 25) which differ significantly from each other by their pulse widths and maximum powers. The maximum power of the first pulse range (23) is higher, at least by a factor of 20, than that of the second pulse range (25). The pulse (24) having the two pulse ranges (23, 25) is generated in that feedback in the laser resonator is interrupted by an analyser and a lambda quarter platelet at the beginning of the pumped light pulse, and in that the feedback losses after a predetermined time are reduced towards zero by a characteristic time constant between 100 ns and 1  mu s, preferably 450 ns, by switching a Pockels cell. In order to obtain the above ratio of maximum powers, the feedback losses are reduced to 5 x 10<-2> of the loss-free feedback. A defined readiness to absorb radiation of healthy and carious hard dental material is achieved with the first pulse range (23), while the second pulse range (25) removes hard dental material. <IMAGE>
